FWIW, the latest black boards have the cap problem (post #2) corrected. It was only in the first version (blue board??).

It looks like the marking for C1 on zeonrider's boards are backwards as well. According to the schematic I posted in post #2 of this thread the positive side of C1 should connect to C4 and R15. On the boards it is reversed.

While we talking mini alephs, does anybody have any input on the power supply CRC question I posted in the ps thread?Mini Aleph Power Supply

Both the black and the early red boards are good for mini-A, Aleph 3/Aleph 30, Aleph 5, or Aleph 60. They share the same basic schematic but have different rail voltages and bias point and number of output devices.

Keep in mind, Brian didn't use the same part number as Papa's service manual, but it can be easily done to create a BOM for A5 using the black board parts number. Send me an email via the forum ....
